HEAT DISTRIBUTER OR'PLATE.

Application filed February 26, 1913. Serial No. 750,767.

To aZZ whom. it may concern Be it known that I, STUART B. ll 11.1: a, acitizen of the United States, residing at (,Ihicage, in the county ofCool; and ritatc of Illinois, have invented certain new and uscfulImprovements iii a Heat Distri intcr o Plate, of which the following isa description.

My invention belongs to that general ci. of devices known as heatdistributers or plates, and relates particularly to a device for use incooking and preparing food, which food may be in suitable utensils, ormay be placed upon the top of the plate, depending upon the article tobe cooked, or it may be used for heating articles other than food. Thedevice is particularly adapted to be used for baking purposes in whichcase cover may be placed over the same, the material to be baked beingplaced under the cover. When the device is so em ployed, food may bebaked on the plate as satisfactorily as in an oven. F

The invention has among its objects the production oi a device of thekind described that is simple, convenient, durable, eliicient, andsatisfactory, and that may be manufactured and sold at small cost.

To this end my invention consists in the novel construction, arrangementand com'lnnation of parts herein shown and described. and moreparticularly pointed out in the Claims.

In the drawings, wherein like reference characters indicate like orcorresponding parts, Figure l is a top plan view of the device. Fig. 2is a cross sectional Vii-3W oi the same. taken substantially on line 2,2 of Fig. 1. Fig. 3 is a sectional View of a portion of a modifiedconstruction, and Fig. T isa top elevation oi the same.

Referring to the drawings, my preferred distributer consists of asubstantially flat top plate 1,. which is provided with two or moreseries'oi' holes or openings 2 and 3, arranged substantially as shown.The holes are of any preferred size, and there may be as many asdesired, or as the space will permit. The top plate may be providedwith. ribs, or ridges 4i and 5, and when the distribute! is made of thinsheet metal, as shown in the drawings, the ribs or ridges may be formedby corrugating the plate. In the construction shown. the ribs extendproximate to the center of the plate, and a space is left as at 6, inwhich the name of any suitable manner, when tle the manufacturer may oeplaced. The ribs are adapted to support and raise the cool; mg utensilsslightly above the plate 1, an alFu tend. to strengthen or stillen thetop plate.

Iii-ranged below the top plate. a plate T, which is formed as shown mostclearly 1'" 1g. 2, or in an equivalent manner, and

in extended or flanged asgat 8 about the periphery. This plate may besaid to be convex, or concaYo-convet, with the cone-arc s1 le toward thetop plate, so as-to form a heating chamber between the two. The cXtendedflat flange 8 bears against or contacts with the under inc? of the plate1, the same being of sulliciont width to extend 'l ronrthe pe ripheryol'the top plate to a point between the opei'iings or holes 2 and llolesJ are provided in the flange 8, the same being of 7 the same size andthe one in number as the holes 2, so that when the two plate" are curedtogether the holes :2 and register.

The two plates may be sccuretl together in l none; I

constructed of sheet metal. top plate 1 flanged downw and thence turnedinmu'r brace a flange 10 on the flanges 1,0 and 11. when are quite stillor rigid. an; the plate over a burner or course, understood that thestruction is shown, in wl plateili is provided with slots 16, and aplate cured below the plate 13, ll a same cxte from and being seen. l toor: u points between the ends of the low two plates may be seen 18, ortheir eipiivalent on the top plate similar struction. This .con. .uoperation to the other cr. explanation of the operation sullice forboth. Assumin tl l1 positioned over aliaiue. r. n passes up through theholes same being directed to the holes b vex face of the lower plate.an. within the heater by the l'lang s ll) A portion of the heat is coducted oi.. the'lower plate 7, and heats the plate 1, the excess heatpassing out through the holes In some cases a top or cover prer-siouslynicotinned is not desirable. With it, however,

pies, cake, bread, biscuits, or meats, and the I like, may be baked inthe same manner as if no an'oven, and toast may be made upon the plate,or fiat irons heated thereon. A pan or pot will serve as a cover forbaking purposes, or a special cover may be provided for the purpose.

Having thus described my invention, it is obvious that Variousimmaterial modificati'ons may be made in the same Without deli partingfrom the spirit of my invention, hence I do not Wish to be un'clerstoodas.

limiting myself to the exact form,construe 1- tion, arrangement, orcombination of parts herein shown and described, or uses mentinned. a VJhat I claim as new and desire by Letters Patent is:-

1. A portable heat distributenfw cookto secure ing utensils comprising.a top plate having radiating ribs extending from a point adjacent thecenter thereof to a point adjacent the periphery thereof and also havinga series of openings arranged in'alternate relation with regard to saidribs adjacent the outer terminal thereof, a lower substantiallysemi-spherically-shaped plate secured at its upper edge to the undersurface of the upper plate at a point beyond the ribs and soles, thelower plate being adapted to re-- ceive the direct action of the flameand separated from the upper plate by an unob-. structed space, theupper plate having a depending annular supporting flange and the upperancl lower plates having an annular serles of reg stered holes at apoint adgacent said; flange, substantially as and for the purposedescribed.

2. A portable heat distributing i'nember comprising an upper platehaving a down-i wardly pro ecting edge flange extending therearo'und toconstitute a support, a concave-convex lower plate, the lowermostcentral portion thereof being substantially parallel to the lower edgeof saidfiang'e, and the upper outer edge being in Contact with. theupper plate adjacent the outer edge of the latter, the lower plate beingseparated thev upper-plate by an unobstructed space" and said lowerplate being free fromopenings leading into said space, the upper-platehaving a-series of openings communicating with said space between theplates, and an auxiliary series of openings therethrough. adjacent theouter edge thereof in communication with the space between the undersurface" or the lower plate and the inner surfaee of said supportingflange.

I 3 A portable heat distributing member comprising an upper circularplate, having a downwardly projectingperipheralsupporting flange, saidupper plate haying t-Wo concentrically arranged annular series ofopenings acljacent'said peripheral flange, a lower plate having aconcave-convex central portion connecting with a fiat peripheralportionat the upper edge thereof the peripheral flange of the upper platehaving'a bent portion overlying the lower edge of said supporting flangeof the lower plate.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses. v
